FCZone Custom CRM
Challenge: Credit brokerage work is fragmented across messages, spreadsheets, documents, and bank-specific requirements. That slows processing and increases errors.
Approach: Built with Supabase and Next.js, using Cursor and LLM workflows to structure client data and generate bank-ready packages with a clear status pipeline.
Impact: A scalable operational system that reduces manual handling and creates a foundation to connect website forms and calculators directly to CRM processing.
